potential U of any body at a large distance r from its center of mass to an external test point is presented via Maxwell's representation for homogeneous harmonic functions in the form of a superposition of directional derivatives of the fundamental solution r1 of the Laplace equation U = 0....

tau starts and accumulates in a heterogeneous manner across different regions in various individuals. In this regard, it is imperative to consider that the different networks being progressively affected by AD pathology may be largely determined by underlying macro-scale axes of cortical organization in...

The initial rotation is such that the final stretch is accomplished without any change of direction in the principal axes of the ellipsoid; seeFigure 3.8. Note that R is a rigid rotation of the small neighborhood of X, not of the body as a whole; R can be a function of position, so ...
